To all whom it may concern:

Be it known that l, Evans Hansen, a citizen ot' the United States, and aresident ot'the borough of Brooklyn, city of New York, in the county ofKings and State of New York, have invented certain new and usefulImprovements in Slitting and liewinding Machines, of which the followingis a specification.

The present invention relates generally, though not exclusively, toslitting and rewinding machines, and has more particularly reference tomeans for eflectivcly separating side by side sections of flexible sheetmaterial.

Certain materials, such as tinfoil, adhesive tape and other materials ofa tacky or sticky nature when slitted into sections have a tendency toreunite at the adjacent edges of the slit-ted sections during remindingon the same shaft or side by side. It has been attempted to overcomethis defect by revvinding the sections on separate shafts, but this isdisadvantageous because in that Way the sections will be rewound intocoils of varyingr diameters which consequently exert dif ferent pulls ondifferent sections at the plane of severance with the result that theslitting is distorted and is not edected. evenly. It is thereforepreferable that the slitted sections be rewound on the same shaft orside byhide in order not to sheet adversely the, slitting-operation.'With this side by side rewinding construction attempts have been madeto edect a physical separation of the slitted sections by passing orguiding them through combs or a plurality of series of pins,transversely arranged in each series, and each series having the pins orcombs spaced farther apart than the preceding comb or series ofpins.While this cdectually spreads the sections and physically separatesthem, it has a decided disadvantage in that the side edges of thesections are apt to be turned and folded back on themselves so that whenrewound under pressure the turned-back edge becomes embedded in thecoil. lln slitting and revvinding tinfoihtor instance, the coil, owingto the heavy pressure exerted in rewinding', becomes practi' cally asolid piece of metal in which the turned-back edge becomes embedded andtrend which it cannot be separated,

The main object of this invention is to spread slitted sections ofmaterial Without turning back the edges.

Other objects Will appear as the specification proceeds.

(line feature; of the invention consists in bodily deflecting theslitted sections into laterally spaced relation, as distinguished fromdeflecting the side edges of the material. lhis bodily deflection of:the section is out of the plane of the web or out or the plane ofseverance and is effected with a progressively increasing pitch so as tolet erally separate the sections. The slitted sections which are thusbodily deflected are then brought back into one plane and re-- ivgund inlateral spaced relation side by s1 e. 7

Another feature out the invention con." sists in a spacing or spreadingdevice con sisting of two straight rollers, and a member, composed ofone or more parts, located intermediate the two straight rollers andhaving; inclined surfaces of progressively increasing pitch laterally,together With. means forguiding the sections over said rolleggs andmember. Suitable means are also provided for holding the sections undertension. In-the preferred form herein disclosed, this is ellected bymounting the first straight roller rotatably and in providing means forretarding the rotation of the said roller, together with means forexciting a pull on the sections.

' Preferably also the inclined surfaces are arranged in two seriesextending in opposite directions, each series having a progressivelyincreasing pitch. i

A still further feature of the invention resides in adapting thisspreading or spat ing device to a typeot slitting machine embodying thescorecut method in which the cutting roller against which the cuttersact also does duty as the second straight roller, the member with theinclined surfaces being located intermediate it and the first roller,and the Web sections being led from the cutting roller to the firstroller, then under the member with the inclined surfaces and then back:to the upper part of the cutter roll. This cutter roll may. if desired,also form a part of the rewinding mechanism,

Other features of constr lClJlOH, combina: tion of parts and arrangementof elements will appear as the specification proceeds.

In the accompanying dra rings the invention is disclosed in severalconcrete and preferred forms, from which, however, changes may be madewithout departing from the legitimate and intended scope of theinvention as expressed. in the appended claims.

1 indicates the cutter roll of a slitting and rewinding machine withwhich cooperates s plurality of cutting members, one of which is shownat is straight roller located in front of th cutter roll and rotatablymounted in the bracket 4.. is the spacing or spreading member locatedintermediate the cutter roll 1 and the roller 3. In the embodiment ofthe invention shown in Figs. 1, 2, 3 and l, the member Sconsists of sshaft ii provided with a plurality of cone shaped members 7 arranged intwo series ext-ending laterally in, opposite directions from the centralmember 7 which is straight. The cone-shaped mei'nhers a ororrressivelyincreasing pitch its best seen in Fig. 4, so that '5 has a, greaterinclination than 7*, and l has 'ier inclina tion than 7 and so on, Inpresent instance, the members i ere secured to the sbar't s by meansscrews 9 or otherwise' ll. brake band 9 secured to the pin 10 on thebrecltet e and passes over the roller 3 and thenceover the pin 11. Thelower end of the brake bend is weighted as at 12 The cutter roll 1 formsa part of the rewinding mechanism and together with the roller 13 andpressure roller 14 acts on the coils 15 on the rewinding shaft 16 torewind the slitted memos sections, the members enumerated exerting apull on said sections.

The web 17 is passed up between the roll 1 and cutters 2 where it isslitted into sections. These sections then pass to the roller 3 at theunderside. thereof, up around the same, thence to the underside of themember 5 and up over the cutter roll 1 to the rewinding shaft 16.

The sections in passing from roller 3 to the cutter roll 1, under themember 5, are deflected bodily out of the plane of the web, without thenecessity of engaging the side edges of the sections. Owing to theconstant increase in pitcl: of the cones, the first section, next to themiddle section is deflected, say 1/64 inch, while the second sectionisdetieeted Q/G-elinch and so on; each section being separated from itsnext preceding section. The sections in passing to the cutter roll 1 arel hen all brought back into one plane, but remain laterally separatedand are then rewound side by side in laterally spaced relation. Thebrake band 9 serves to retard the rotation. of the roller 3 and preventsa saelt from, accumulating between the rollers 3 and l and the member 5,which slack would interfere with the control of the sections. It will beseen that the deflection of the sections out of the plane of the web bythe action ot the member 5, amounts to a tilting, or rotating, of thesections about their longitudinal whereby the lateral edges of thesections are laterally deflected. The engagement of the tilted sectionsat a later stage in their movement with the roller 1, produces :3-tilting of the sectionsin the reverse direction about one of thelaterally deflected erilges, with the consequent, bodily lateraldisplacement of the sections as a whole,

The bracket is adjustably mounted. on thers'tuds 1'2", which latter areseated in the open hearings 18. adjusting the studs 17 in said bearings18, the member 5 may be moved to the position found most advantageous ina given set of circumstances.

The coneshaped members 7 may be provided with segments 19 constitutingabutments to prevent undue slippage of the sections. The shaft 6 of themember 5 is adjustably mounted in the bracket a but is normally held inone position by 11 cans of the pull sprin 20 secured to one end of thebelt 21 passing; over the puller 22 on the end of shaft 6 The other endof the belt 21 passes to the foot lever 23, the upward movement ofwhich; under the influence of the spring 20, is limited by the stop 24:.When threading the sections through the machine the foot lever 23 may bedepressed thereby imparting half a turn to the shaft 6 and bringins, thesegments 19 uppermost, thereby iacilitating the threading operation.After the sections are threaded the lever 23 is rethey fur varying-g"the ififieciimi betwaen SQCiLiUHEi ziu 5L pi'ngiessi'veiy changiiig and.subs'tmb m liI- ig s. 5, (i iia'ily mristani; wire, and means for def:ct illfllnb k. 05E iiig; the sestinma aboiii the nthei." edge a:icijmmbiy pix i; 31 1163 in the commit-y dii'ectimn "whereby 7?
